1. BD Diesel Deep Transmission Pan: Best Overall
The BD Diesel Deep Transmission Pan is a top contender for 68RFE owners seeking maximum cooling and durability. Its cast aluminum construction with integral cooling fins helps reduce transmission temperatures, which we verified through owner reports showing drops of 20-30 degrees Fahrenheit under heavy towing. The pan increases capacity by about 3 quarts, providing more fluid for heat management. It includes a magnetic drain plug and a dipstick for easy fluid level checks.
However, this pan commands a premium price. Some owners noted that the dipstick tube may require minor modification for perfect alignment on certain model years. If you are on a tight budget or only need minimal extra capacity, this pan might be overkill. It is best suited for those who tow heavy loads or live in hot climates.
- Increases fluid capacity by approximately 3 quarts over stock
- Cast aluminum construction with cooling fins for improved heat dissipation
- Includes magnetic drain plug and dipstick for easy maintenance
Pros: Excellent build quality and fitment reported by owners; Significant temperature reduction under load
Cons: Higher price point compared to some competitors
2. Suncoast Diesel Deep Pan: Runner Up
The Suncoast Diesel Deep Pan offers a solid balance of capacity, durability, and price. With a 6.5 quart capacity, it provides a meaningful increase in fluid volume. Owner feedback highlights easy installation and a perfect seal using the included gasket. The black powder coat protects against corrosion and looks clean under the truck.
One limitation is that its cooling fin design is less extensive than the BD pan, so maximum heat reduction may be slightly lower. It is an excellent choice for daily drivers and moderate towing, but extreme performance users might want more aggressive cooling. Skip this if you need the absolute lowest temperatures.
- 6.5 quart capacity, adds about 2.5 quarts over stock
- Cast aluminum with black powder coat for corrosion resistance
- Includes magnetic drain plug and dipstick
Pros: Great fitment with no modifications needed on most trucks; Durable powder coat finish resists chipping
Cons: Cooling fins are less aggressive than some competitors
3. PACCAR Deep Transmission Pan: Best Value
The PACCAR Deep Pan is a budget-friendly option that still increases fluid capacity. Its steel construction is sturdy, and the e-coat provides decent corrosion resistance. Owners report good fitment and no leaks. It includes a drain plug for easy fluid changes.
However, steel is heavier than aluminum, and the coating can chip over time leading to rust. Also, the lack of an included dipstick is an inconvenience. This pan is ideal for those on a budget who want extra capacity but do not need the cooling benefits of aluminum fins. Skip if you want maximum heat dissipation or a lightweight pan.
- 6 quart capacity, adds about 2 quarts over stock
- Steel construction with e-coat for rust protection
- Includes drain plug, dipstick sold separately
Pros: Very affordable price point; Simple design with reliable sealing
Cons: Steel is heavier than aluminum and may rust if coating chips; No dipstick included, must purchase separately
4. Fass Deep Transmission Pan: Premium Pick
The Fass Deep Pan is a premium offering with billet aluminum construction and a high 7 quart capacity. Its machined cooling fins are effective, and the included magnetic drain plug and dipstick add convenience. Owners praise its build quality and temperature reduction.
However, the high price is a barrier for many. Additionally, the pan’s shape may interfere with aftermarket exhaust systems on some trucks. It is best for enthusiasts who want the best materials and are willing to pay a premium. Skip if you have a tight budget or a modified exhaust.
- 7 quart capacity, billet aluminum construction
- Machined cooling fins for efficient heat transfer
- Includes magnetic drain plug and dipstick
Pros: Premium billet aluminum looks great and dissipates heat well; High capacity for serious towing
Cons: Expensive, often the highest price option; Some owners report fitment issues with certain exhaust systems
5. Mishimoto Deep Transmission Pan: Engineered Cooling
The Mishimoto Deep Pan focuses on cooling with its extensive finned design. It offers a 6.5 quart capacity and cast aluminum construction. Owners note noticeable temperature drops during towing. The pan includes a magnetic drain plug.
However, the lack of an included dipstick is a drawback. Also, the gasket can leak if not torqued to spec, as reported by a few owners. This pan is a good middle-ground option for those who prioritize cooling but do not need a dipstick. Skip if you want a complete kit with dipstick.
- 6.5 quart capacity, cast aluminum with extensive finning
- Designed for improved fluid flow and cooling
- Includes magnetic drain plug, dipstick not included
Pros: Aggressive fin design for effective cooling; Good value for the features offered
Cons: Dipstick not included, must reuse stock or buy separately; Some owners report gasket leaks if over-torqued
6. Aisin Deep Transmission Pan: OEM Style
The Aisin Deep Pan is an OEM-style replacement that offers a slight capacity increase. It is stamped steel and includes a drain plug. Owners appreciate the low price and straightforward installation.
However, the capacity gain is minimal, and the lack of cooling fins means no significant temperature reduction. This pan is best for those who just want a drain plug and a little extra fluid without spending much. Skip if you need substantial cooling or capacity for heavy use.
- 5.5 quart capacity, modest increase over stock
- Stamped steel construction with OEM-style design
- Includes drain plug, dipstick not included
Pros: Lowest cost option, very affordable; Simple installation with no modifications
Cons: Smallest capacity increase of all pans reviewed; Steel can rust over time, no cooling fins
7. Revolution Gear Deep Pan: Budget Option
The Revolution Gear Deep Pan is an affordable aluminum option that includes a dipstick. It offers a 6 quart capacity and comes with a drain plug. For the price, it provides good value on paper.
However, owner feedback indicates fitment problems on newer 68RFE transmissions, and the thin aluminum can warp if not installed carefully. This pan is suitable for budget-conscious owners with older trucks who are comfortable with potential adjustments. Skip if you want a guaranteed fit or a more robust build.
- 6 quart capacity, aluminum construction
- Includes drain plug and dipstick
- Budget-friendly price
Pros: Includes dipstick at a low price point; Lighter than steel pans
Cons: Reported fitment issues on some 2013+ models; Thinner aluminum may warp if over-torqued
Frequently Asked Questions
Does a deep transmission pan really help with cooling?
Yes, a deep pan increases fluid capacity, which allows more time for heat to dissipate. Many pans also include cooling fins that increase surface area for better heat transfer. Based on owner feedback, temperature drops of 10-30 degrees Fahrenheit are common under load.
Will a deep pan fit on my stock 68RFE transmission?
Most deep pans are designed as direct replacements for the stock pan. However, some may require minor modifications or clearance checks, especially with aftermarket exhaust systems. We recommend checking manufacturer fitment notes and owner reviews for your specific model year.
Do I need to change the transmission filter when installing a deep pan?
It is highly recommended to replace the filter and fluid when installing a new pan. The deep pan itself does not affect the filter, but since you are draining the fluid, it is good practice to change the filter at the same time.
What is the advantage of a magnetic drain plug?
A magnetic drain plug attracts metal particles that accumulate in the transmission fluid. This helps keep the fluid cleaner and allows you to inspect the plug for signs of wear during oil changes.
Can I use a deep pan with a stock transmission cooler?
Yes, a deep pan works alongside your stock cooler. The increased capacity helps the cooler maintain lower temperatures. Some owners upgrade the cooler for maximum benefit, but it is not required.
